LAMP.

SPECIFICATION forming part of Letters Patent No. 704,299, dated July 8,1902.

Application filed February 19, 1902. Serial No. 94,849. (No model.)

To mZZ whom it may concern:

Be it known that I, FREDERICK JAMES OLEARE, machinist, of the city ofMontreal, Province of Quebec, Canada, have invented certain new anduseful Improvements in Lamps; and I do hereby declare that the followingis a full, clear, and exact description of the same.

Myinvention relates particularly to safetyto lamps; and it has for itsobject to adapt a hand-lamp to be self-extinguishing upon the reversalor breaking thereof.

The inventionmay be said, briefly, to consist in mounting a movabledevice adjacent to the exit end of the wick-passage of a handlamp andproviding means whereby said device will at times be automatically movedacross said exit end of the wick passage, thereby extinguishing,itlighted,the protrudto ing end of the wick.

For full comprehension, however, of my invention reference must be hadto the accompanying drawingsiorminga part of this specification, inwhich like symbols indicate the same parts, and wherein Figure 1 is alongitudinal vertical sectional view of a handlamp furnished with myinvention. Fig. 2 is a horizontal sectional view taken on line A B,Fig. 1. Fig. 3 is a plan view of the under side of the burner removed;

and Fig. 4: is a similar view to Fig. 1, but illustrating the lamp inthe act of falling from a table with my improved extinguisher performingits function.

The burner b, which may be in the main of ordinary construction,comprises the usual tubular wick-passage c, wick raising and loweringspindle (Z, and chimney-supporting tray 6, while a downwardly-projectingexteriorly 4o screw-threaded collar f screws into aninteriorly-screw-threaded collar constituting the mouth of the reservoirh, to be presently described.

Myimproved extinguishing device consists of a plate L, carried rigidlyupon the upper ends of a pair of levers j, 'fulcrumed about midway 0ttheirlength upon the spindle d,one a short distance from each end of thewickpassage 0. The lower ends of the levers are connected to the ends ofa retractile helical spring k, located in a casing constituted by acurved bead Z, projecting downwardly from the periphery of the tray 6.Two stationary chimney-retaining fingers 'm are secured upon the tray,and said tray is formed with a pair of eccentric slots a, convergingtoward the center of the tray, through which a pair of angular stripsproject, the upper portion 0 of each constituting chimney-retainingfingers, while the lower horizontal portion is slotted near its end andadjustably secured to the under side of the tray by pins 19. Each ofthese angular strips has a lug q upon its under side, which is connectedby a link 1" to the lower end of one of the lovers 7'. The normalcondition of these parts will be with the lower ends of the loversyieldingly held in a position to cause the plate i to extend across theexit end of the wick-passage, which will of course prevent theprotruding end of the wick being lighted.

In order to set a chimney upon the tray, the fingers 0 should be drawntoward one another and away from the stationary fingers n a sufficientdistance to allow said chimney, which is indicated at s, to be set inplace. Upon the fingers 0 being then released the spring will draw themin against the chimney, thus holding it firmly, while the chimney inturn prevents the return of the fingers 0 under the influence of thespring, thus also retaining the extinguisher away from the lighted wick.

It is obvious that upon the removal of the chimney the extinguishingdevice will extinguish the wick if lighted, and the same will take placeif the lamp should be accidentally tipped over, as shown .in Fig. 4, orallowed to fall.

What I claim is as follows:

1. In a lamp comprising a wick-passage and a chimney-support, thecombination with said wick-passage, of a movable device consisting of aplate, a pair of levers fulcrumed between their ends one at each end ofsaid wick-passage and carrying said plate at their upper ends, aretractile spring connected to the lower end of said levers forretaining the same yieldingly in a position with said plate across theexit end of said wick-passage, a movable device bearing upon the chimneycarried upon the chimney-support and moving when said chimney isremoved, and a link connection between said movable device and the lowerend of said levers, whereby said plate will be caused to move to aposition across said wick-passage upon the removal of said chimney,substantially as described and for the purpose set forth.

2. In a lamp the combination with a wickpassage and a chimney-supportingtray having a pair of stationary chimney-retaining fingers, of a movabledevice consisting of a plate, a pair of levers fulcrumed one at each endof said wick-passage and carrying said plate at their upper ends, aspring connected to the lower ends of said levers for retaining sameyieldingly in a position with said plate across the exit end of saidwick-passage, a pair of yielding fingers bearing upon the chimneycarried by the tray, means for movably connecting said fingers to saidtray and a pair of links connecting said movable fingers to the lowerends of said levers, substantially as described and for the purpose setforth.

3. The combination with a burner comprising a passage for the illuminantto 'be burned and a tray for supporting a chimney said tray having apair of eccentric slots converging toward the center thereof, of amovable device, yielding means for retaining said device across saidpassage, a pair of angular strips each having a portion projectingupwardly through said slots, the other portion of each being slidablyconnected to the under side of the tray and means for operativelyconnecting said angular strips to said movable device, substantially asdescribed and for the purpose set forth.

4:. In a lamp the combination with a chimney-supporting tray having apair of chimney-retaining fingers, a wick-passage a wick raising andlowering spindle; of a plate; a pair of levers fulcrumed upon saidspindle one at each side of said wick-passage and car-- rying said plateat their upper ends; an annular flange of rounded cross-section integralwith and depending from the periphery of'
